At A Glance

  • Fertilizer Type: Fertilizer spikes
  • Apply: Early Spring & Late Fall
  • Item Weight 14.1 ounces

The First fertilizer on our list is the Jobe’s 01661 Fertilizer Spikes. For Norway spruce, this is the best fertilizer available in the market because of its superior features.

Let’s look at why we’ve selected it as our most favorite and why it’s unique from the rest- 

The uniqueness of this product is the fertilizer type! This product comes in the type of pre-measured evergreen fertilizer spikes. This fertilizer spike will reach the active roots of the Norway spruce. Hence, the tree will be greener and stand stronger while facing winds. 

If you ask us then we’ll tell you that the main benefit of applying fertilizer spikes is that the fertilizer spikes are easier to handle. Moreover, they’re even easier to store than granular fertilizer sacks. 

Here, the use of fertilizer spikes can stimulate biological activity in the soil. Thus, it will promote disease resistance and pest resistance.

Oftentimes, people think that once a tree is grown we might think that it won’t need any fertilizer anymore. This is a wrong idea. A shrub or tree always needs a continuous supply of nutrients to grow. 

So, spike fertilizer is the best way to provide them with nutrients. 

Besides, the Norway spruce grows in acidic soil. And the spikes of “Jobe’s Evergreen Fertilizer” are for all acid-loving plants and shrubs. 

It’s no secret that beautiful, healthy trees enhance the appearance of your yard. So, to make them healthy use these fertilizer spikes.

The roots of the Norway spruce will get the best nutrition through the spikes. Therefore, these spikes will ensure that the tree gets a continuous supply of nutrients.

And, they will supply the tree below the surface because this is where the tree’s active roots grow. 

Other than that, this is time-release fertilizer. It will slowly release the nutrients thus it will last all season. Again, the slow-release solution acts at the active roots of your trees.

On the other hand, the Jobes fertilizer spikes are super easy to apply. In fact, anyone can apply them to the ground.

There will be no wasteful runoff or any type of mess while applying them on the surface. Additionally, there is no bad smell either. 

First, you have to water the area of the tree. Then you will need a hammer to make the job easier. Then find the drip line of the Norway spruce. 

After that, apply the spike directly under the drip line. Next, place the spiky or pointy side of the spike fertilizer on the ground. 

Now, aim for the plastic cap with your hammer. And start hammering it into the ground.

After that keep a distance of 3 meters and keep placing the spikes circularly. Easy right? Anyone can do that without any professionalism in gardening. 

Lastly, if you want to keep a specific time frame about the application process then you’ll need to apply the fertilizer on the Norway spruce in early spring and late fall.

This product follows a different style compared to the first product. Here, the previous product was a time-release fertilizer. But, the BioAdvance fertilizer is a slow-release fertilizer. 

The slow-release fertilizer, basically, has a coating around it. This coating breaks down due to sunlight, water, or soil microbes. 

 The advantage of slow-release fertilizer is that it won’t overdose on your plant. Hence it will get the nutrition gradually and effectively for a long time.

Therefore, slow-release nitrogen fertilizer spreads throughout the plant, from the roots to the branch tips.

Here, the Humic DG is a highly concentrated carbon-based, organic soil amendment that comprises 70% fulvic acid, humin, and humic acid. It is created with Dispersible Granule (DG) technology, which is patented by The Andersons. 

When each Humic DG granule comes into contact with water, it disperses into thousands of tiny particles. Now, these particles go directly into the root zone. Then the granules provide instant benefits to the soil and plant.

All types of soil can benefit from this fertilizer Humic DG technology. Which can also help to reduce watering requirements. It promotes water storage and minimizes evaporation in sandy soils. It allows for deeper water and root penetration in clay and other dense soils.

Miracle-Gro Plant Food is number four on our list. This fertilizer will provide a sufficient amount of nutrition to your Norway spruce. And, it will increase the greenery of the trees while making them stronger. 

As we all know Norway spruce is a very good windbreaker, this fertilizer ensures that it’ll stand high and strong. Enough of the description, let’s look at why it’s unique- 

The most unique thing about the Miracle-Gro plant food is that it’s formulated with kelp, feather meal, earthworm castings, and bone meal. These particles feed the microbes of the soil. Then the Microbes break down organic materials into nutrients that promote root health and growth. Thus it also increases water efficiency.

Kelp is high in micronutrients. It also aids in the opening of root systems in trees, allowing the trees to better absorb nutrients from the soil. Moreover, Kelp is a strong bio activator too. So, it facilitates the breakdown of compost and therefore improves soil conditions.

Besides, the minerals found in earthworm castings include high nitrates, magnesium, potassium, phosphorus, and calcium. That can boost plant production, protect trees from disease, and improve soil moisture retention.

Whereas, Feather meal provides more constant plant growth whether utilized indoors or outdoors.

Nutrient enrichment happens immediately, followed by a long, gradual feed that provides widely accessible nitrogen while lowering the risk of nitrogen burning.

Another benefit of this fertilizer is that it’ll supply calcium production. Calcium is provided by bone meal to your trees.

5. Schultz Slow-Release Plant Food

At a Glance

  • Type: Slow-release
  • Size: 3.5 lbs
  • Product Dimension: 12 x 10 x 7 inches
  • Fertilizer Analysis: 12-6-6
  • Application Time: Any Season

The last product on our list is the Schultz Slow-Release Plant Food. If you think this plant food is any less than its predecessors then you are mistaken, my friend.

This one just came last on our list. Still, it’s one of the best fertilizers in the market, we believe that. 

The uniqueness of Schultz Slow-Release plant food is that it contains nitrate nitrogen. Plants use nitrates to obtain nitrogen, which is required to produce proteins for healthy growth. Nitrates in water are absorbed by plants via their roots. This plant fertilizer contains significant quantities of nitrates.

Now, the amount of chlorophyll in leaves might decrease when there is a lack of nitrates. This causes the leaves to turn a yellow or pale green color. 

Therefore, it limits the plant’s capacity to photosynthesize and grow properly. So, to enhance nitrate levels, you can use the “Schultz Slow-Release Plant Food”. 

This plant food also contains iron. Iron assists in the movement of oxygen throughout the plant’s leaves, roots, and other sections.

Resulting in a greenish color that indicates a healthy plant. Iron is also required by many plants to fulfill the enzyme processes that keep the plant alive.

This plant food will help your Norway spruce grow greener and stronger. It will feed your tree or shrubs for 3 months. 

Moreover, it is a slow-release fertilizer. So, there is a coating around the fertilizer granules that slowly breaks down and supplies nutrition for long 3 months. Keep applying after every 6 weeks. 

It also promotes vigorous root growth. Vigorous root growth and dense and long root hairs will ensure the effective absorption of macro-and micronutrients. This will happen during the early growth of your Norway source. 

How and When to Fertilize Norway Spruce? 

best fertilizer for norway spruce

First, you have to understand if your spruce even needs fertilizer. Because fertilizer should be applied only when spruce shows signs of nutritional deficit. Or maybe it has a poor growth rate. 

After analyzing if you think it needs to be fertilized. Then you should apply fertilizer in the early spring to reap the best benefits.

Before and after fertilization, give a spruce enough water. This is very essential but if you are using any fertilizer that is granules. Be careful while watering the tree because the granules might wash away. Thus you will get no result. 

If the nitrogen application rate is no more than 2 pounds per 1,000 square feet. Then a drop spreader can be used to distribute the fertilizer over the ground, under and slightly beyond the spruce branches. 

After that, thoroughly water the area. A higher rate of application using this method could result in the burning of any neighboring grass or vegetation.

Another way to apply fertilizer is by boring holes in the ground 2 feet apart in concentric circles. That commencing 3 feet out from the trunk of a larger spruce.

Or slightly closer for young trees is an alternative fertilizer application method ideal for fertilizing larger plants. 

Furthermore, soak the area surrounding the tree well. Then use an auger or metal rod to make holes 2 inches across and 8 to 12 inches deep. 

Next, fill the holes with fertilizer at a rate commensurate to the fertilizer’s nitrogen content or as suggested on the label.

Now, if you’re using a 10-8-6 fertilizer, put 2 1/2 tablespoons in each hole; if you’re using a 21-0-0 fertilizer, use only 1 1/4 tablespoons in each hole.

Or read the instructions on the fertilizer package. Because each of the above fertilizers is unique and can be applied differently. 

What Happens When You Fertilize Norway Spruce? 

Spruce trees do not require a lot of phosphorus and will gain the most from an acidic fertilizer developed for evergreens or a high-nitrogen fertilizer with a formula like 10-8-6 or 12-6-4.

Now, compost, cottonseed meal, alfalfa meal, and fish emulsion are all organic fertilizer choices. As they decompose, 3- to 4-inch layers of organic material should be applied such as shredded bark or well-rotted compost. 

These will conserve moisture and also control soil temperature, and give nutrients to the soil. After that, the trees can get the required nutrition from the soil.

Frequently Asked Questions

Question: What is the best way to fertilize a Norway spruce tree?

Answer: Fertilize the Norway spruce tree once a month, starting when new growth appears in the spring. Apply a 20-20-20 fertilizer at the recommended rate on the package.

Fertilization should be stopped in August. Check for mite infestations on the Norway spruce.

Question: When should I fertilize my spruce trees?

Answer: A 5 foot wide Norway spruce would cover 25 square feet. Fertilizer “maintenance rates” of 2 to 4 pounds actual nitrogen per thousand square feet of the soil surface.

You can apply every two to four years, which is normal. One pound of actual nitrogen is probably adequate for mature, slower-growing trees.

Question: How can evergreen trees be turned greener?

Answer:  Your evergreens may have trouble absorbing nutrients in highly sandy locations where the soil pH is more basic. If your trees appear to be unusually pale green, they may want some nitrogen.

Never put fertilizer in your evergreens’ planting holes directly. Use a balanced, slow-release fertilizer or one formulated specifically for evergreens if you want to fertilize at all.

Question: How effectively does the fertilizer Spikes work?

Answer: Spikes work by slowly releasing nutrients into the soil. Hence these organic and natural solutions only introduce high-quality nutrients into the soil.

Therefore, Bacterial and Fungal activities cause the release. This action increased resistance to disease and pests in the trees. 

Question: What is the significance of root growth?

Answer: Root development is crucial for the establishment of newly planted seedlings. Stress occurs when the root system of a newly planted seedling is unable to give enough water to transpiring needles.

In order to maintain a proper water balance and assure survival.
